* Added new TAG: DDC for "this feature is document". After we are sure
that all source code variables/commands/functions/ are tagged with either
DDD or DDC we'll remove them.
* Made module Makefile.am's more centralized by moving common stuff
to acconfig/module.mk.
* Introducted new help system. It's now on per module basis and localized.
Default language is "en_EN" else not otherwise specified. Beside the
%b formattings of 1.6 it has all features of the 1.6 help system.
It's also more intelligent since help files are automaticly bound to
module load/unload events. You don't need to manually load module help
files any more. (Though unloading not tested yet... 8-))
* Fixed some tweaks here and there.
